I'm with Rick on this one ,race boards are hard to surf and you will fall of a lot ..and you are limited to going straight ,well thats what they are designed for

but you will catch waves on it for sure ,and there is some fun involved ...
but a 10 foot board is the perfect beginner size ,or even a 11,11,4 nalu ,or simular long board size ..you will be able to move it around in the right position ,
and have more fun ,,

line the wave up ..go right out the back and paddle onto the wave ..then move up the back so they don't nose dive ,
have fun ..i remember my first lump i caught on a SUP ,i was smiling for days ,,20 boards later here I am ..LOL.
i still have 14's and enjoy them in 1 foot waves ,there surely is a art surfing them ,and those who can do are usually
fantastic surfers .
